Which of the following statement is correct for paper chromatography?
  1. Water present in the pores of the paper forms the stationary phase.
  2. Paper sheet forms the stationary phase.
  3. Water present in the mobile phase gets absorbed by the paper which then forms the stationary phase.
  4. Paper and water present in its pores together form the stationary phase.

Solution

The principle of paper chromatography is partition. In paper chromatography there are two phases one is the stationary phase and the other is the mobile phase. Here, water trapped in the paper acts as the stationary phase and solvent acts as the mobile phase.
